Nowadays, with the changes of the times, everyone's requirements for security are getting higher and higher. This is especially true for the museums that hold value-added cultural relics. Most of these museums will purchase museum vault gates to protect them. The theft of the molecule, its protective performance is very good, but the saying goes, but the use of troops for a thousand days to use troops, we buy the museum vault gate is to prevent that moment, but how to raise it will, and then that, in fact, in fact, Our understanding of the museum's vault door is not very thorough. As a staff member of a multi-year security facility, Xiao Bian tells everyone that if your museum vault gate has the following conditions, then you need to pay attention.

Locks have changed
If you find that your lock is not so accurate, then it is possible that the molecular structure inside will change. At this time we need the help of the factory. For example, if the problem occurs, the factory will arrange technicians to commission it on site if the consumer Careful words, generally in the handover, the technical staff will tell us these things.
Open up effort
This problem is very common, we often can receive such after-sales calls, such problems are generally caused by the lock bolt, and the reason for this is that usually we are too violent during use, and often lock It is not completely aligned. We have opened the violence. It is difficult for the door lock to be damaged for a long time.
A perfect product, quality is only a prerequisite, and later maintenance is also very important, as is the museum vault gate. If you want to have a museum museum vault door with perfect performance, then you must start with routine maintenance.
CPE 135A
Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
